Abstract: ABSTRACT           A centrifugal pump with hydraulic thrust balance and tandem axial seals.  The centrifugal pump has  an  impeller with  front  and  rear axial  seals operating in unison to either reduce or increase the size of gaps therebetween.  The gaps are of a minimal dimension to minimize leakage.  The rear axial seal is located at the tip of the impeller with the front axial seal  located either at the  impeller eye or radially outwardly thereof.  Hydraulic thrust balance is  achieved  and  continuously  maintained  by  axial movement  of  the  impeller  shaft  and  impeller  to modulate the gap at the rear axial seal and, thus, control the value of an effective pressure acting on the back side of the impeller whereby an outward thrust force resulting therefrom counterbalances an inward thrust force resulting from pressure acting on the front shroud of the impeller.  A clearance at the rear  of  the  impeller communicates  with  suction pressure  through  a  restricted  passage.   Impeller hydraulic thrust balance forces usually dwarf other thrust forces which are considered to be external thrusts without significant impact on overall thrust balance.  Examples of external thrusts are those that arise from suction pressure acting over the process seal area and from helical gears in integral gear driven systems.  A normally preferred thrust balance design  is  appropriate  for  the  majority  of  pump applications, but design alternatives are offered for inordinate pump applications which provide maximum capacities  to  handle  either  outward  or  inward external thrust loads.

Title: Coin validator
Inventor: YOSHIHARA KENZO
IPC: G07D5/02
Filed: 1989-05-19
Granted: 1992-07-07
Abstract: A coin validator of a static capacitance system for discerning the thickness and/or pattern of a coin in a noncontact manner. A pair of electrode assemblies including a first and a second sensor electrodes and a first and a second guard ring electrodes are disposed on the corresponding sides of a coin path. The first and the second guard rills electrodes prevent the dispersion of electric lines of force generated by the first and the second sensor electrodes. The first and the second sensor electrodes are impressed with resonating output signals from resonators. Under such condition, when the coin passes through the coin path between these electrodes. the entire inter-electrode capacitance changes to fluctuate the resonating output voltage and hence allow the thickness and/or pattern of the coin to be detected. The guard ring electrodes serve to focus the electric lines of force into a beam to thereby allow the thickness of the coin to be detected finely.

Abstract: ABSTRACT            A rain shield for a circuit-interrupting device is provided that includes a housing for attachment to the circuit interrupter adja-cent  an exhaust  outlet  of  the circuit interrupter.   The rain shield prevents the ingress of moisture while providing a path for the exhaust gases of the circuit interrupter.  The rain shield is selectively attach-able to the circuit interrupter and is reusable.  In one arrangement, the rain shield includes a housing which is generally cylindrical and has an inlet opening at a first end for cooperation with the exhaust outlet of the circuit interrupter.   At a second opposite end of the housing, an outlet is defined that includes a predetermined pattern of openings.  A centrally disposed plate is provided adjacent the outlet and functions as a drip cap.  The drip cap is dimensioned in accordance with the predeter-mined pattern of openings in the outlet, such that moisture in the form of precipitation that enters the outlet of the rain shield is prevented from entering the inlet opening adjacent the circuit interrupter. When the circuit interrupter is in an inverted position,  precipitation that directly  enters  the  openings  in  the  outlet  of  the  rain  shield are collected in a reservoir area of the housing.   The reservoir  in  one particular configuration is formed between an inner wall that defines the inlet opening and an outer wall of the housing.  Drain holes are provided through the outer wall of the housing that communicate with the reservoir such  that water  accumulating  in  the  reservoir  is  drained  from  the inverted rain shield.  In the preferred arrangement, the housing of the rain shield cooperates with an attachment fitting at the exhaust end of the circuit interrupter such that the rain shield must be assembled to the circuit interrupter and the attachment fitting as a final assembly before the circuit interrupter can be retained within a mounting.

Abstract: EXACTLY-ONCE SEMANTICS IN   A TP QUEUING SYSTEM               ABSTRACT      Exactly-once semantics in a transaction processing system are provided by queuing requests for data base transactions on a "task queue" and assigning a unique identification number to each request or "task" placed on the queue.  When a requested transaction is performed, the task identification number is written into the data base when the data base is updated at the end of the transaction.  To ensure that the updates are made exactly once in the event of a partial system failure or "crash", the data base is read to obtain any preexisting task identification number before any updates are made.  If a match occurs between the identification number of the current task and any preexisting task identification number, the requested transaction is terminated without performing any current updates.  Automatic recovery with exactly-once semantics therefore occurs as the result of resumed servicing of the task queue. A task which is initiated is not removed from the task queue until after its requested transaction is completed.  When servicing of the task queue resumes during recovery from a partial system error, the data base has stored on it all of the identification numbers.
